just for the purpose of learning the technique I will give you sizes to cut, however you can do this technique with any size or shape block or center.
Cut a 6 inch block of background fabric and of...
Cut the same size and shape from freezer paper
as your background. I did this with an archway once.
I use one of my acrylic circle or drunkard's path templates. You will choose the size of opening you want.It must be small enough to leave a seam allowance on the background but large enough to showcase your focus fabric.
Iron the FP to back of your background. In this case, fold it in half, roughly cut out the center leaving about a half inch seam allowance, and clip almost to the FP
using a water soluble glue stick, UHU is best, run a small amount of glue along the clipped edge and a bit of the paper
Using your finger, open the clipped fabric and push over the edge of your FP so that it sticks to the paper smoothly. This will be the exact edge of your opening so you want it to look perfect. If you have a glitch, you might need to clip closer
Since this is a picture heavy post I will do the next sections later. Please
